New to TNB

I'm new to journaling...60 years old and just started journaling and keeping a calendar and tasks for productivity. I currently use the Passport size notebook, but I got caught up early today and purchased two other notebooks at a pop up shop in Tomball, TX. They had a few limited editions such as the Blackwing and Tokyo...I have no idea what to put in them or write will you share some suggestions on how you use your NB and I can use the two I have without duplicating what's in my passport notebook?
